Abstract

BACKGROUND

Malnutrition is a significant problem in Africa. In Kenya, 26% of under-fives are stunted; slums are the hardest hit. Obunga slum has the highest prevalence at 40%.

METHODS

A cross-sectional study was adopted; simple random sampling techniques were used to identify 189 eligible households in the Obunga slum with children between 6-24 months. An interviewer-administered questionnaire collected data on food price perceptions and food and beverage marketing. An anthropometric data collection form gathered information on the children's height, weight and age. Scores for stunting, wasting and underweight were generated based on WHO Z-Score cut-off points. Binary logistic regression identified the relationship between food price perceptions, food and beverage marketing and the nutritional status of children between 6-24 months in Obunga slums.

RESULTS

Prevalence of wasting was 3.2%, stunting was 27.0%, underweight was at 7.4%, while overweight was at 13%. Food price perceptions: An increase in fruits prices was significantly associated with wasting (Adjusted O.R. = 10. 82, C.I. = 1.10-106.77, P < 0.05) and underweight (Adjusted O.R. = 5.44, C.I. = 1.35-21.61, P < 0.05). Food & Beverage Marketing: Feeding children on commercially produced complementary food products and commercially produced food was significantly associated with wasting at an (Adjusted O.R. = 7.82, C.I. = 1.29-47.46, p < 0.05, and adjusted O.R. = 5.96, C.I. = 1.06-33.60, p < 0.05) respectively. Stunting was significantly associated with listening/reading or watching advertisements on commercial food products (Crude O.R. = 0.49, C.I. = 0.24-0.998, p < 0.05.). Watching food-related adverts on television (Adjusted O.R. = 0.38 C.I. = 0.146- 0.10) and watching marketing on commercial foods (Adjusted O.R. = 0.21, C.I. = 0.07-0.61) and watching television (Adjusted O.R. = 9.30, C.I. = 2.31-37.40). While watching food-related adverts on television was associated with being underweight (Adjusted O.R. = 18.68 and at C.I. = 1.22-286.89).

CONCLUSION

The price perceptions of fruits, feeding children commercially produced food products and complementary foods, and Watching food-related adverts on television; had an impact on the nutritional status of children. Thus, a longitudinal study would be needed to understand the long-term effect of food prices and food and beverage marketing on nutritional status.

摘要

背景

营养不良在非洲是一个重大问题。在肯尼亚，26%的五岁以下儿童发育迟缓；贫民窟受影响最为严重。奥本加贫民窟的患病率最高，达40%。

方法

采用横断面研究；运用简单随机抽样技术，在奥本加贫民窟确定了189户符合条件的家庭，这些家庭中有6至24个月大的儿童。通过访员管理的问卷收集有关食品价格认知以及食品和饮料营销的数据。一份人体测量数据收集表收集了有关儿童身高、体重和年龄的信息。根据世界卫生组织Z评分临界点得出发育迟缓、消瘦和体重不足的分数。二元逻辑回归确定了奥本加贫民窟6至24个月大儿童的食品价格认知、食品和饮料营销与营养状况之间的关系。

结果

消瘦患病率为3.2%，发育迟缓为27.0%，体重不足为7.4%，超重为13%。食品价格认知：水果价格上涨与消瘦（调整后比值比=10.82，置信区间=1.10 - 106.77，P<0.05）和体重不足（调整后比值比=5.44，置信区间=1.35 - 21.61，P<0.05）显著相关。食品和饮料营销：用商业生产的辅食产品和商业生产的食品喂养儿童分别与消瘦显著相关（调整后比值比=7.82，置信区间=1.29 - 47.46，p<0.05，调整后比值比=5.96，置信区间=1.06 - 33.60，p<0.05）。发育迟缓与收听/阅读或观看商业食品广告显著相关（粗比值比=0.49，置信区间=0.24 - 0.998，p<0.05）。观看电视上与食品相关的广告（调整后比值比=0.38，置信区间=0.146 - 0.10）、观看商业食品营销（调整后比值比=0.21，置信区间=0.07 - 0.61）以及观看电视（调整后比值比=9.30，置信区间=2.31 - 37.40）。而观看电视上与食品相关的广告与体重不足相关（调整后比值比=18.68，置信区间=1.22 - 286.89）。
